A comprehensive analysis of the evolution of the structural and superconducting properties of FeSe crystals stored in air for several years has been performed. It is established that the structure and phase composition of the samples remained invariable, while the superconducting parameters significantly degraded. These changes may be due to the stress relaxation or redistribution of defects in the samples. 相似文献

Layered oxycarbonate Bi2Sr4Cu2CO3O8 single crystals have been obtained for the first time by free growth in closed vapor-phase cavities. The morphology, structure,
composition, and superconducting properties of these crystals have been investigated. 相似文献

Single crystals of topological insulators—bismuth chalcogenides Bi2Te3, Bi2 ? x Sn x Te3, Bi2Se3, and Bi2 ? x Cu x Se3 with different charge-carrier densities—are grown by the modified Bridgman method. Their composition and structure are investigated and temperature dependences of the electric resistance and magnetic field dependences of the Hall voltage are obtained. 相似文献

The influence of post-growth short-term low-temperature annealings (O2, 400°C, 5–15 min) on the composition, crystal structure, and superconductivity of Bi2Sr2CaCu2O8 + δ and Bi2Sr2CuO6 + δ oxycuprate whiskers freely grown in gas cavities has been investigated. The optimal conditions for growth in closed gas cavities in a flux and post-growth annealing in oxygen were found, making it possible to obtain high-quality superconducting Bi 2212 and Bi 2201 whiskers in a wide doping range (from heavily underdoped to optimally doped) with a small rocking curve half-width (~0.1°–0.2°) and narrow superconducting transition (ΔT = 1.5–2 K). 相似文献

Superconducting crystals of iron selenide FeSe are grown and their phase and elemental compositions are studied. The structural analysis of individual FeSe1 ? x crystals showed the coexistence of two phases in this compound. The resistivities and magnetic susceptibilities of the crystals are investigated. 相似文献
